When the sun goes down, we're turning to Lezyne's Super Drive 1600XXL Headlight to guide our way home. This bike light is high-powered, and it features three high output LEDs for up to 1600 lumens of output. That's a heck of a lot of light in our book! It has seven modes and Lezyne's Tri-Focus Optics optimize light output so you'll have vision and clarity on your ride. This light is micro-USB rechargeable - a convenience that lets you recharge as needed - and can run for up to 148 hours on a full charge so you'll never worry about running out of light. A stretchy, versatile strap secures this light to all common handlebar sizes, and an auto day/night sensor automatically adjusts lumen output in certain, select modes.
